...Both PBMCs and splenocytes were cultured in complete medium for 7 days.Each culture was supplemented with recombinant human IL-6 (10 ng/mL; R&D Systems, Minneapolis, MN) and granulocyte macrophage-colony-stimulating
factor (10 ng/mL; R&D Systems) in the presence or absence of DXM and incubatedin humidified air with 5%CO2 at 37°C. Cells culturedin medium alone were runin parallel as controls. Adherent cells were removed using a nonprotease
cell detachment solution Detachin (Neuromics, Edina, MN)
. CD331 cells were isolated by anti-CD33 magnetic microbeads and LS column separation (Miltenyi Biotec, Bergisch Gladbach, Germany), per manufacturer's instructions. The purity of the isolated cells was found to be higher than 90% by flow cytometry...
